WATER-CLOSET.

SPECIFICATION forming part of Letters Patent No. 275,838, dated April 17, 1883.

Application filed November 2, 1882. (No modelf) To all whom it may concern Be it known that I, JAMEs 0. MOLAUGH- LIN, of Cincinnati, Hamilton county, ()hio, have invented certain new and useful Improvementsin W'ater-Olosets, of which the following is a specification.

My invention relates more particularly to that class of water-closets which is used in cities, and in which water is used to flush the bowl after using; and the object of my invention is to provide means for preventing the escape of any odor or noxious gases into the This is particularly desirable when the water-closet is placed in a bath or other room.

Referring-to the drawings, forming part of this specification, Figure 1 represents the seat of the closet with the lid thrown back. Fig. 2 is a vertical central section of the same, showing the lid slightly raised. Fig.3 represents a portion of the plate by which the bowl is secured to the under side of the seat. Fig. 4 represents an annular flange for securing the bowl to the under side of the seat. Fig. 5 is a vertical central section of a closet,showing a modified means for securing the bowl to the under side of the seat. Fig. 6 shows the preferred form of catch for securing the lid.

A is the seat, provided with the usual hole, A, and to the back part of this seat is hinged the cover B. Around the hole A in the seat A is a circular channel, a, and to the under side of the lid B is secured a circular elastic gasket, 1), so placed as that it will enter the channel a when the lid is closed down, completely preventing the escape of any odor between the seat and the lid. The lid is pro vided with a suitable catch for holding itfirmly down on the seat, the-preferable form being that shown inthedrawings. A knob, G, is secured to the upper side of thelid nearits front edge, and this knob has a spindle, D, which passes through the lid and projects far enough to pass through the seat when the lid is closed down, an opening, d, being formed in the seat to allow the spindle to pass through.

To the under side of the seat A is connected a spring-stud, G, having a head,g, beveled at the end, as shown, the beveled end projecting past the inner opening of the hole (1, and in the end of the spindle D, which projects past the lower face of the seat, is formed a notch,

g, into which the beveled end of the springstud enters when the lid is down, thus firmly holding the lid down upon the seat.v The end of the spring-stud and the notch g, in which it rests, being beveled, as shown, the lid may be readily raised and lowered.

E is the bowl of the closet, which is secured to the under side of the seat, and in some suitable manner, whereby the junction between the seat and bowl is gas-tight. A preferable mode of joining the seat and the bowl is as follows: The top of the bowl is provided with a surrounding flange, 6, between which and the under side of the seat is placed an elastic gasket, 0' The bowl is preferably held in contact with the seat by means of the annular flange F, through which pass bolts or screws f, which are secured to the under side of the seat, and when these bolts or screws are tightened the flange F presses against the under side of the flange e of the bowl, thus holding it firmly against the seat, and the gasket 0 being interposed between the bowl and the under side of the seat, no odor or gas can escape from the bowl. Preferably, the bolts should not pass through and appear at the top of the seat. A preferable means of preventing such construction consists as follows: A plate, F, is secured to the under side of the seat above the annular flange F, and the headsf of the boltsf being above this plate, the bolts are firmly connected to the seat, and nuts f being screwed onto the lower portion of these bolts after they have been passed through the annular flange F, the latter is firmly secured.

If desired, instead of using the annular flange F, the bowl maybe constructed as shown in Fig. 5, lugs g being formed With the bowl at intervals around its upper edge, and these lugs being provided with holes through which the bolts orscrews f pass, which bolts onscrews are secured to the seat, as in the former instance. By the above construction no odor or gas can escape from the closet when the lid is down.

It is obvious that this invention may be usedin connection with earth-closets or commodes as well as with water-closets.

Experience has taught me that a great deal of the odor arising from water-closets comes from the trap which is usually provided in water-closets as now constructed, as the decaying matter is in most instances retained for considerable time in such traps and gives off odor, which passes into the room. For this reason I construct my water-closets without traps, a pipe, H, leading from the bowl direct- 15' into a main pipe, H, with which main pipe the closets on the various floors communicate, and at the lower end of this main pipe is formed one large trap, cutting it 011' from the sewer. Into this main pipe, above the trap, I also conduct all wash-water and water from the bath-tubs, which keep it at all times thoroughly flushed out, leaving no decaying matter to give 011' odor, and the one main trap cuts off all communication with the sewer. A "entilating-pipe, h, is preferably connected to each bowl, which connects with a main ventL lating-pipe, and thus gives a free circulation of airin the pipes. Any of the ordinary forms of valves now in use maybe placed in the pipe H to retain a small amount of water in the bowl.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is as follows:

1. The seatA, provided with circular groove or channel a, in combination with the lid B, hinged thereto, and provided with the circular elastic gasket 12, adapted to fit into said channel when the lid is closed, substantially as and for the purposes specified.

2. The combination of the seat A, having circular channel a, and the lid 13, having circular gasket 1), adapted to-fit into said channel, and a catch, substantially as described, for holding the lid firmly in contact with the seat, substantially as and for the purposes specified.

3. The combination of the seat A and lid B, provided with an interposed elastic gasket 1). and the bowl E, secured to the under side of the seat, and a packing or gasket, 0, interposed between the npper edge of the bowl and the seat, substantially as and for the purposes specified.

4. The combination of the seat A, provided I with plate F, the bowl E, provided with surrounding flange e, and the annular flange F, connected to the plate F by boltsf, the heads of the latter being above the plate F, substantially as and for the purposes specified.

5. The combination of the lid B, provided with spindle D, having a notch, g, and the seat A, provided with opening (I, and springstud G, secured to the under side of the seat. and provided with a beveled head, g, adapted to engage with the notch g, and an elastic gasket interposed between the lid and seat,

substantially as and for the purposes specified.
